The about 500 km long coastal stretch of central Dronning Maud Land (DML), East Antarctica, is critical for understanding both Gondwana and Rodinia assembly. In common reconstructions DML lies at the potential southern extension Mozambique Belt. We report first extensive geochronological study magmatic metamorphic rocks from area. These new U‐Pb SHRIMP zircon Sm‐Nd‐data sampled during German international GeoMaud 1995/96 expedition indicate that oldest in are Mesoproterozoic age....

Abstract A dataset to describe exposed bedrock and surficial geology of Antarctica has been constructed by the GeoMAP Action Group Scientific Committee on Antarctic Research (SCAR) GNS Science. Our group captured existing geological map data into a geographic information system (GIS), refined its spatial reliability, harmonised classification, improved representation glacial sequences geomorphology, thereby creating comprehensive coherent geology. total 99,080 polygons were unified for...
Abstract The late tectonic history of the southern part Late Neoproterozoic–Early Palaeozoic East African–Antarctic Orogen (EAAO) is characterized by lateral extrusion, extensional collapse and large volumes high-temperature A 2 -type granitoids. This late-tectonic igneous province covers an area more than 15 000 km EAAO in Dronning Maud Land (East Antarctica) its northerly continuation as Nampula Complex NE Mozambique. magmatic bounded north Lurio Belt. New secondary ionization mass...
The post‐Carboniferous crustal evolution of the German Continental Deep Drilling Program (KTB) area, as summarized in this paper, could not be predicted from surface observations: deep drilling was essential for its revelation. most conspicuous and unexpected feature discovered drill hole is absence marked gradients with respect to pre‐Carboniferous record. There are no depth‐related differences K‐Ar cooling ages hornblende white mica, petrology or lithology. All metamorphic rocks...

Abstract The post-Caledonian tectonic history and landscape evolution of southwestern Norway are poorly understood, primarily owing to the lack onshore post-Devonian sediments. To bridge this knowledge gap, low-temperature thermochronological techniques were applied investigate vertical movements in upper crust. New apatite fission track zircon (U–Th)/He analyses on samples from yielded Permian Jurassic, Triassic Cretaceous Carboniferous ages, respectively. Thermal modelling indicates...
